Nissan Skyline R34 GT-R V-Spec: The Ultimate Japanese Supercar

The Nissan Skyline R34 GT-R V-Spec (BNR34) is universally regarded as one of the greatest Japanese performance cars ever built. Produced from 1999 to 2002, the R34 GT-R represented the pinnacle of Nissan's ATTESA E-TS AWD technology, the legendary twin-turbocharged RB26DETT 2.6-litre inline-6 engine, and advanced aerodynamics that cemented its status as a supercar killer. At Grovexo JDM, we source 100% genuine, authentic Nissan Skyline R34 GT-R parts worldwide — ensuring you get only the best OEM and JDM-spec components.

What Made the R34 GTR Special?

The R34 GT-R built on the legendary R32 and R33 platforms but introduced significant improvements. The RB26DETT engine was factory-rated at 276 hp (the infamous Japanese gentlemen's agreement), but real-world dyno tests consistently showed 320+ hp from the factory. The ATTESA E-TS Pro AWD system with active LSD front and rear provided unmatched cornering ability. Nürburgring lap records fell before the R34, and the car earned the nickname Godzilla — destroying all competition regardless of budget.

R34 GTR Variants: Which One to Buy?

The R34 GT-R came in several important variants. The V-Spec (Victory Specification) added Brembo brakes, NISMO carbon driveshaft, and a mechanical rear LSD. The V-Spec II upgraded to carbon fibre hood and subtle aero refinements. The ultra-rare V-Spec II Nür used the NISMO-tuned N1 engine block with improved casting and oil flow — only 718 units were made, making it among the most collectible modern Japanese cars. The M-Spec was a luxury grand touring version with Ripple Control dampers. Finally, the M-Spec Nür combined luxury with the N1 engine for the ultimate touring variant.

RB26DETT Engine: The Heart of the Beast

The 2.6-litre twin-turbocharged inline-6 RB26DETT is the beating heart of the R34 GT-R. With individual throttle bodies, forged internals in the N1 spec, and a cast iron block, the RB26 is famous for its immense tuning potential. Stock internals reliably handle 500+ hp with upgraded turbos. With built internals, 800-1000+ hp is achievable. Key genuine JDM parts for the RB26 include: Genuine Nissan RB26DETT head gasket (11044-24U01), OEM RB26 valve stem seals, Genuine Nissan water pump (21010-05U26), OEM R34 GTR timing belt kit, and authentic Nissan HKS-spec cams.

ATTESA E-TS AWD System: Engineering Excellence

The ATTESA E-TS (Advanced Total Traction Engineering System for All-terrain, Electronic Torque Split) system was revolutionary. Under normal conditions the R34 runs rear-wheel-drive; when sensors detect slip, up to 100% of torque is instantaneously transferred to the front axle. The V-Spec adds an active front LSD for additional cornering control. Maintenance requires genuine Nissan ATTESA fluid and pump components — aftermarket substitutes can cause premature failure of the transfer case and viscous coupling.

R34 GTR Suspension & Brakes: Track-Ready from the Factory

The R34 GT-R uses multi-link suspension front and rear with Bilstein dampers. V-Spec models receive Brembo 4-pot front calipers with 324mm rotors — a massive upgrade over base GT-R brakes. For serious track use, popular genuine parts include Stoptech brake pads compatible with OEM Brembo calipers, Genuine R34 front knuckles for camber correction, and OEM front and rear sway bars. The factory steering is hydraulic rack-and-pinion — one of the last great hydraulic setups before electric power steering dominated.

R34 GTR Values & Market: 2026 Update

The R34 GT-R became legally importable to the USA in 2024 (25-year rule), causing prices to surge dramatically. Clean stock V-Spec examples now command $150,000–$250,000 USD in the US market. V-Spec II Nür examples have sold for $400,000+ at auction. In Japan and other markets, pricing remains lower but values are rising globally. As an investment, the R34 GT-R has appreciated faster than many traditional supercars, making sourcing genuine OEM parts increasingly important for maintaining value.

Popular R34 GTR Performance Upgrades

The most popular upgrade path starts with the turbos — the stock ceramic turbos are reliable but limiting. Most enthusiasts upgrade to Garrett GTX2860R or HKS GT2530 bolt-on turbos, which push power to 500+ hp on stock internals. Genuine Nismo 740cc injectors and a Greddy or Trust fuel pressure regulator support the fueling. The HKS FCON or Apexi Power FC standalone ECUs are the gold standard for R34 tuning. A TRUST intercooler upgrade and Mines or N1 exhaust manifold complete the stage 1 build, typically producing 450-500 wheel horsepower.
